Mathpls

A silly Cloudflare Worker serverless function that takes an algebraic expression and calculates the result, returning it in JSON format.

Supported operations:

• +-*/ operators
• () expression grouping
• functions from Math.*
• constants pi (𝜋) and e (Euler's number)

Simply add your algebraic expression in the URL path and the service will reply with the result in JSON format.

The JSON returned conforms to the following TS type:

type Result = { result: number; error: null } | { result: null; error: string };

Examples

• Circumference of the Earth along equator, in meters: https://expr.run/2*pi*6.378137e6 ($d = 2 \pi r$)
• Approximate period of a 3m pendulum at sea level, in seconds: https://expr.run/2*pi*sqrt(3/9.81) ($T = 2 \pi \sqrt{L \over g} $)
